Answer:
If a neurotransmitter attaches to a ligand-gated channel and creates a potential that causes the inside of the excitable cell membrane to become less negative, and this potential travels only a short distance before dying out, it is considered to be a depolarized graded potential.
Step-by-step explanation:
We talk about a graded potential when a small change in membrane potential occurs is proportional to the size of the stimulus, usually they do not travel long distances along the neuron membrane, but a short distance and decrease as they propagate to end disappearing. If a graded potential is strong enough it can lead to action potential.
The depolirization occurs when a stimulus reaches the neuron producing an electrochemical change or disturbance where ions (Na) enter the cell, and in this way the membrane potential becomes less negative (more positive). It propagates along the membrane, but when it reaches the axon, the release of neurotransmitters occurs, which when in contact with the adjacent neuronal membrane exerts on it the action of a stimulus (that is, ionic changes are made).
